A lot of our members have found the breaking point of big blocks in our 8 second cars and have updated to Indy or Keith Black blocks. A lot of us know better than to put Edelbrock Victor heads, w7,W8,W9 heads on our stock blocks because we would soon find the breaking point of stock blocks. I’m not saying they won’t handle it. But they wouldn’t handle racing like many of us do every week. Way to much money spent on the top end to risk it.
